DETAILED DESCRIPTION

[0027] A protective device 1 according to FIGS. 1 to 10 is provided as a shading device for a glass roof region of a passenger vehicle. The shading device is provided in the vehicle interior below the glass roof region and has a flexible fabric 2 which is also referred to as a shading web. The flexile fabric 2 is held on a winding shaft in a manner such that it can be wound up and unwound, the winding shaft being mounted rotatably in a cassette housing K mounted on the roof (FIG. 8). The flexible fabric 2 is provided on its opposite side edges with a respective stiffening strip 7 which is guided in a longitudinally displaceable manner in a guide track which is in each case mounted on the roof and therefore mounted on the vehicle and is in the form of a guide rail 6. Only one of the roof-mounted guide rails 6 is shown with reference to FIGS. 1 to 10. An opposite side of the protective device 1 including the guide rail 6 is configured mirror-symmetrically relative to a vertical center longitudinal axis, but otherwise identically. In order to avoid repetitions, only the one side is described below with reference to the drawings according to FIGS. 1 to 10. The same applies equivalently to the opposite side.

[0028] The flexible fabric 2 is shiftable along the guide rails 6 between an inoperative position, i.e. a first functional position, wound up onto the winding shaft and a second functional position pulled out as far as an end region of the guide rails 6. The two stiffening strips 7, which are assigned to the opposite side edges of the flexible fabric 2 and are guided in the vehicle-mounted guide rails 6, serve to exert a permanent transverse stress on the flexible fabric 2 transversely with respect to the longitudinal shifting direction. This avoids sagging of the flexible fabric 2. The flexible fabric 2 is connected on its end region that is at the front in the pulling-out direction to a dimensionally stable pull-out profile 3 which extends in the transverse direction over the width of the fabric 2. The pull-out profile 3 is illustrated in two different positions with reference to FIG. 1. The pull-out profile 3 is coupled at its opposite ends to a respective guide element 4 which is guided in a longitudinally displaceable manner in the respective guide rail 6. In the exemplary embodiment illustrated, the guide element 4 is shiftable longitudinally in the respective guide rail 6 by means of a drive system. A longitudinal shifting of the pull-out profile 3 and therefore of the guide elements 4 can take place in the same manner, but also manually by corresponding grasping of the pull-out profile 3 and displacing same along the guide rail 6.

[0029] The respective stiffening strip 7 is connected fixedly to the guide element 4 in order to be able to be carried along by the guide element 4. The stiffening strip 7 is designed as a flat strip and is produced from steel or a fiber-reinforced plastic strip. The stiffening strip 7 is wound together with the flexible fabric in the region of the cassette housing K onto the winding shaft and is pulled off therefrom. The stiffening strip 7 projects at its end region that is at the front in the pulling-out direction beyond the flexible fabric 2 (see FIGS. 5 to 7). In this region, the stiffening strip 7 is perforated by a total of five holes which constitute passages 8 within the meaning of the invention. The passages 8 are configured identically to one another and are arranged one behind another at uniform distances in a row. All of the passages 8 are of circular design and are preferably produced by punching. The front end region of the stiffening strip 7 is connected in a manner described in more detail below to a holding part 9 which is subsequently fitted into a receiving profiling 17 of the guide element 4. The holding part 9 consists of an upper partial region 12 and a lower partial region 10 which are connected pivotably to each other via a film hinge 11. A pivot axis formed by the film hinge 11 extends parallel to a transverse extent of the pull-out profile 3. The lower partial region 10 is provided with a total of five pin-shaped profiling portions 16 which protrude toward a common side from the strip-shaped partial region 10. In the illustration according to FIGS. 5 and 6, the pin-shaped profiling portions 16 protrude downward.

[0030] The upper partial region 12 has five plug-in receptacles 15 in a complementary manner to the pin-shaped profiling portions 16, said plug-in receptacles at least partially having plug-in cross sections which are complementary to the cross sections of the pin-shaped profiling portions 16.

[0031] As can be seen with reference to FIGS. 5 to 7, for the connection of the holding part 9 to the stiffening strip 7, first of all the upper partial region 12 is placed onto the front end region of the stiffening strip 7 until the plug-in receptacles 15 align with the passages 8. In this position (FIG. 6), the film hinge 11 is approximately level with a front end edge of the stiffening strip 7. Subsequently, the lower partial region 10, which still extends forward in the manner of a tongue from the upper partial region 12, is pivoted downward in accordance with the arrow depiction in FIG. 6, as a result of which the five pin-shaped profiling portions 16 enter successively through the passages 8, which are arranged one behind another, and enter into the plug-in receptacles 15.

[0032] It can be seen with reference to FIG. 10 that the plug-in receptacles 15 and the pin-shaped profiling portions 16 are extended in a radial plane with respect to the pivot axis which is formed by the film hinge 11. In addition, it can be seen with reference to FIG. 10 that all of the pin-shaped profiling portions 16 and the associated plug-in receptacles 15 are curved in the shape of a circular arc. The circular arcs here have different radii which correspond to the different distances of the individual pin-shaped profiling portions 16 from the pivot axis formed by the film hinge 11. Accordingly, the curvature of the pin-shaped profiling portions and of the associated plug-in receptacles in the shape of a circular arc decreases in relation to the distance at which the individual profiling portions and plug-in receptacles are from the pivot axis of the film hinge 11. The tongue which forms the film hinge 11 extends around the front end edge of the stiffening strip 7 in the completely mounted state of the holding part 9 (see FIGS. 7 and 10). The pin-shaped profiling portions 16 are either held purely in a force-fitting manner in the plug-in receptacles 15, or the profiling portions 16 and the complementary plug-in receptacles 15 are assigned additional latching profilings (not illustrated specifically) which secure the plugged-in end position of profiling portions 16 and plug-in receptacles 15. Since, in addition, the profiling portions 16 are plugged in a form-fitting manner through the passages 8 of the stiffening strip 7, the holding part 9 is fixedly connected to the stiffening strip 7.

[0033] In the upper partial region 12, the holding part 9 is additionally provided with a connecting portion 13 which is configured as a substantially T-shaped profile. In a complementary manner with respect thereto, the guide element 4 has a receiving profiling 17 which is provided with a complementary T-shaped plug-in groove which is open forward in the pulling-out direction. On the rear side, the receiving profiling 17 is provided with a rear wall 18 serving as an end stop. The holding part 9 is pushed with its connecting portion 13 into the receiving profiling 17, configured as a plug-in groove, of the guide element 4 in parallel to the direction of extent of the stiffening strip 7 until the connecting portion 13 comes into contact on the end side with the rear wall 18. In addition, the connecting portion 13 is provided with an elastically flexible latching lug 14 which, in the plugged-in end position of the connecting portion 13, latches into a latching groove 19 of the guide element 4 (see in particular FIG. 10). The holding part 9 is therefore firstly plugged into the guide element 4 in a force-fitting and play-free manner and is additionally secured in the latching groove 19 of the guide element 4 in a form-fitting manner via the latching lug 14. The form-fitting support in the opposite direction is taken on by the rear wall 18.

[0034] Accordingly, a longitudinal shifting of the guide element 4 inevitably leads to a corresponding longitudinal shifting of the stiffening strip 7 and accordingly to a longitudinal shifting of the flexible fabric 2.
